How to Build a Serverless Martian Weather Display with CircuitPython and AWS Lambda — When there’s no big news it’s always nice to lead with something a bit fun! This tutorial demonstrates the creation of a standalone digital weather display for Mars (yes, the planet!) including showing the latest images from the Mars Curiosity Rover. AWS Lambda is involved, naturally, but some of the other bits might be new to you including the Adafruit PyPortal and CircuitPython. (This has just made me buy one!)

Serverless Events: A Curated List of Serverless Events — Of course, the best thing about this list right now is that all (but one!) of the events are online, so there’s lots of things you can attend. Most are single talks rather than lengthy events. You’re also invited to submit your events.

Making the Case for Serverless Use Cases — Jeremy writes up nine neat use cases for serverless that he discussed with Serverless Inc’s Gareth McCumskey on the Serverless Chats podcast recently. RESTful APIs, cron jobs, and machine learning all get a look in.

Serverless in the Wild: Azure Functions Production Usage Statistics — A couple of months ago we featured a paper about how Azure Functions allocates and provisions resources based on workload. This article, by an Azure MVP, summarizes the most interesting points in a more accessible way.

Serverless Needs Standardization to Be the Future of Application Infrastructure — A lot of the technologies serverless platforms use under the hood are standardized but the way they work isn’t necessarily as generic and apps built for one platform may not easily transition to another. This needs to change, argues Gadi Naor.

Creating a Scalable Serverless Import Process for Amazon DynamoDB — How to import large amounts of data into DynamoDB from S3 using a parallel serverless approach, initially with a Lambda function alone, but at higher scale with two functions and an SQS queue in between.

Using AWS API Gateway to Run Database Queries — API Gateway is commonly used to hook up HTTP endpoints to AWS Lambda functions but did you know it can directly connect to DynamoDB? (Or any AWS service that lets you query over the AWS API, so not RDS.)

How to Remain Agile with DynamoDB — Amazon DynamoDB delivers performance at scale but at a cost to flexibility (particularly early on in the development cycle when your eventual access patterns aren’t always known) – there are some mitigations, however.

Reusing Redis Connections in AWS Lambda — Of course, this only works if the same hot instance of the function is run again, but callbackWaitsForEmptyEventLoop is well worth knowing about.

TLDR: Writing a Slack bot to Summarize Articles — Using state-of-the-art NLP to read more news, faster? I always find automated summaries to be kinda useless, but the way it’s put together is neat nonetheless.
